That rumored Audi V6 is a diesel engine, which indeed is allowed to use two (VTG) turbochargers. I was talking about the future LMP1 [b]petrol[b] engine rules, which only allow one (VTG) turbocharger and 2 liter displacement.

So let me get this straight, you think the rumored Audi V6 is going to be a production stock unit used for P-1? Or is it because their current P-1 engine is a twin turbo? If it is the latter then twin turbos are also legal on current petrol engines in P-1.

According to Sam Collins the R18 "is to be fitted with a six cylinder twin turbo diesel engine, possibly mated to an energy recovery system." If this is true, obviously this will be clean sheet designed race diesel engine. It is just impossible to get 520+ bhp from a stock V6 TDI.

Others have suggested that Audi will a petrol engine. I argue that then a petrol turbo engine will the preferred option.

Yes, would appear to be the case. But then these aren't the official regulations, just the latest draft:

As I said, Audi hasn't been using racing to push their TFSI gasoline technology since the R8 was retired in '06. With the R10 and R15, it's been diesel this and diesel that, and Audi has been looking into electric hybrid technology off and on for over 20 years.

Toyota still 'own' the hybrid brand, and a sportscar campaign would help Audi and Peugeot erode this

The regs may well favour a petrol/hybrid approach

Toss in the already extant work Peugeot did on the 908HY and this doesn't look at all surprising.

Well. Peugeot are going at the Diesel-Hybrid road, where Audi is going Petrol-Hybrid (for their road cars).
So i do not see a factory Petrol-Hybrid from Peugeot, but maybe Audi.
Peugeot would want to show off that Diesel-Hybrid is better than Petrol-Hybrid, and what way is better that beating them at Le Mans?.
Besides the 908HY was a Diesel-Hybrid, so Peugeot already know that technology in race cars.

They may have. I didn't get to listen too much. Slightly unrelated, but I did catch the SPEED pitwall interview with Norbert Singer and that was very cool. He seemed genuinely excited about the future possibilities.

I think they will go petrol/hybrid. At least Audi anyway. It should be the easier route. The electric motors will more than make up for any lost torque that a diesel would provide. And I think that is generally easier to build a petrol engine lighter than a relative diesel. However, diesel technology in this application is still in it's infancy and is developing very rapidly, so they may go diesel. At this point it is all speculation regardless of who is reporting it. Ultimately both will chose whichever they feel the regs gives an advantage too. And that is something that is unclear to us outsiders. Or they may chose diesel/hybrid just to prove that they can do it. I wouldn't be surprised if Peugeot take this route. They sort of have that kind of attitude.

No matter what...I think that this is the most exciting time in motorsports in a long while. I also think that it will prove to be one of the most important eras as well. We are witnessing the beginnings of a great change and I hope that the R18 and it's contemporaries will reflect that excitement and freshness. If the ACO can keep up, the next decade could be mind blowing.
